To all whom t may concern Be it known that FRED W. Nass, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, has invented new and useful Improvements in Window Screens, of which the following is a specification.

The object of the invention is to provide a window screen whereby a regulation in the ventilation of the room or apartment in connection with which it may be used may be eEected by the interchanging or substitution of fillers or webbings of different degrees of porosity, and therefore more particularly to provide a window screen construction whereby the interchange or substitution of the webbing or filler may `be effected with facility to also aford convenience in the removal of the filler, when of fabric to permit of laundering or of treatment with disinfectant when, for example, the device is used in connection with windows of sickrooms and the like; andv 4with these objects in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the accompanying drawings, wherein Figure 1 is a view in elevation of a screen of foldable type wherein the sections or members are respectively provided with fillers or webs of diiferenttypes or having dierent meshes.

Figure 2 is a view of a screen also embodying the invention wherein the sections or members are slidably connected.`

Figure 3 is a detail view showing a means for holdin a folding `screen of the type shown in *igure 1 in its extended condition.

Figures 4 and 5 are detail sectional views showing the means whereby the filler or webbing is secured to theframe of the screen.

Figure 6 is a detail in perspective of one of the clips used for securing the ller or webbing.

Figure 7 is a plane indicated b Figure 8 is a tion or portion of webbing.

'Figure 9 is a detail sectional view of the marginal portion of a fabric ller or webbing, taken on the plane indicated by the line 9-9 of Figure 8.

The screen frame is preferably of a folddetail sectional view on the the line 7--7 of Figure 2, etail view` of a corner seca metallic screen ller or ing type adapted for ready application to' .hospital wards, sick and removal from the window opening, but may be either' of the hinged type shown in Figure 1 or the sliding or 'extension type shown in Figure 2, the same, in either case,

consisting of relatively movable sections or members adapted to receive and carry fillers or webbing units which in Figure 1 are shown atl() and 11 and which for illustra-f tive purposes are respectively of fabric such or other v as cheese cloth and of wire gauze, materials a-daptable to the purpose, having meshes of such a size as to serve the desired purpose. ln some instances it is only necessary to provide for the exclusion of insects such as flies in which event the wire gauze is `ordinarily found suflicient, especially when a gauze of relatively thin mesh selected, but such a t-ype of webbing affords but slight obstacle to air, and therefore in practice it frequently occurs that it is desirable to employ a web bing or screening material which while admitting light will modify the circulation of air or reduce extent and at the same time will exclude even smaller insects than those which can be barred by the ordinary wire gauze, and to this end it is desirable, as contemplated by the present invention, to provide for insubstituting the filler or webbing to suit the requirements and enable the operator to change the same without inconvenience or loss of time so that the same terchanging or frame may be used for a variety of different purposes or under different conditions, and in this connection to provide means whereby a webbing or filler of fabric may be disposed in such a relation to a window opening as to ser-'ve as a distributing agent 95 for an antiseptic for deodorizing or like agency as for example in connection with rooms and. the like. Therefore the frame of the screen, as more particularly illustrated in 6 is provided with clips 12 of 1ll-shaped, hair pin or looped form embedded in the frame bars 13 which may be provided with suitable openings 14 for that purpose and secured by means of plugs the frame between the arms of the clip with the extremities of the latter extended as shown in Figure a and adapted to be passed through eyelets 16 or openings 1n the webbing or ller 'arallelismy with the frame as shown in Figure 5; Ae a further security or means the circulation of the 75 the same to a greater or less 80 Figures ll, 5 and 100 15 driven into 105 and then folded into of maintaining the vclips in proper lrelatioi'i with the elements of the frame the arms thereof may be provided as shownv with barbs 17 adapted to be embedded in tlie terial of the frame by driving home the plugs 15,'as clearly illustrated in '61.

The webbing or filler whether of Vfabric such as shown at l or or metal screening as at ll should be marginally reinforced to afford the requisite strength and.. to guard against distortion in applying and removing the samel andlsueh reinforcement maybe provided with reference to 'a metallic filler or' webbing as shown in Figures l and 8 by filler or webbing such as metallic strips 18 having the edges of the webbing interposed therebetween and" connected by the eyelets as a means ol" holding the same in place, whereas with a fabric of cheese cloth or the like the edges may befolded as shown in Figure 9 at 19 and stitched as'sliown at 20 with the eyeletextending through the doubled portion as illustrated. .Also as shown at 2l the eyelets in the reinforced marginal portion of ,ya metallie screen forming the webbing or filler may be elongated to conipensate or allow for any variation in the spacing of the clips. K

Having described the invention, what is claimed as new useful is l. A wnd'owpscreen having its Vframe provided with pliable clips, and a filler or webbing having marginal eyelets for engagement by said clips to permit of' interchanging the filler or webbing, the' clips being of looped or hair pin construction with the looped portions thereof embedded in and secured to the frame and with the extremities thereof :extended lor bending into engaging relation with the eyelets oi? the filler or webbing.

2. A window screen having its frame provided with pliable clips,y and a lill-er or webbin having marffinal e eletsl'or en'gaeeg e Y e ment by said clips to permit or interchanging the filler or webbing, said clips being or" looped orhair 'pin construction with' the looped portions thereof embedded in the frame and provided with lateral spursfor engaging the material thereof.

3. A window screen having its :traineprovided vwith pliable clips, and a filler or webbing yhaving marginal eyelets for engagement by said fc'lipsto' permit or interchanging the iiller or webbing,"`said clipsk being of looped or hair pin construction and having the looped portions embedded in openings in the frame, the arms of the clips' being Vpro'- vided with 'lateral spurs engaging in the side walls or' the openings, and plugs driven into the openings between the arms of the clips yto maintain the spurs in suchV engagement.

In testimony'whereof he alliXes his" signature.
